Why black coal is considered to be a metamorphic rock?
Coal is generally considered a sedimentary rock as it is made up of deposited material (in this case organic matter, mostly from plants) and is eventually covered up by overburden. I'm not going to go into the details of the physical change but the reason black coal might be considered metamorphic is that it has been subjected to more pressure over time which furthers the coalification process. The order of coalification coal: peat -> lignite (brown coal) ->sub bituminous -> bituminous ->anthracite (very rare) everything after lignite is black in colour. If you need this for a report I'd probably look it up though, its been a while since I've studied coal in depth.

Which layer is made of solid rock?
The Earth is made up of several layers, divided by sub-layers, divided by even more sub-layers. There is the core, which is mostly made up of solid iron; the outer core which is up to 10% liquid so still contains a lot of solid rock; the lower mantle which is ductile (solid rock that is not completely melted but still solid in a 'plastic' state), the upper mantle which consists of crystalline forms of olivine and pyroxenes among some other solid materials, and then the crust which on average is about 40 km thick. Whereas the crust is made of solid rock, there are other layers that are solid rock as well.

The main sub-categories of sedimentary rocks are clastic, chemical, and organic. Clastic sedimentary rocks form from the accumulation and cementation of fragments of pre-existing rocks. Chemical sedimentary rocks form from the precipitation of minerals from water solutions. Organic sedimentary rocks form from the accumulation and compression of organic materials, such as plant or animal remains.
